Classification: Niessliaceae, Hypocreales, Hypocreomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Saprobic on wood. Sexual morph: Ascomata perithecial, densely gregarious, superficial, globose to subglobose, black, membranaceous, glabrous, ostioles inconspicuous. Peridium composed of dark brown cells of textura angularis. Paraphyses absent. Asci 8-spored, unitunicate, clavate, pedicellate or sessile, evanescent. Ascospores uni- to bi-seriate, hyaline, ellipsoidal to oblong, straight or slightly curved, 1-septate, guttulate. Asexual morph: Undetermined (adapted from Saccardo 1880, Theissen 1910, Jaklitsch & Voglmayr 2011).
Notes – Myrmaeciella was treated as a synonym of Hypocreopsis (Müller & von Arx 1962, Rogerson 1970). Rossman et al. (1999) subsequently transferred Myrmaeciella to Niessliaceae based on their similar membranaceous ascomata, inamyloid asci and ellipsoidal ascospores.
Type species: Myrmaeciella endoleuca (Sacc.) Lindau [as ‘endoleucum’], in Engler & Prantl, Nat. Pflanzenfam., Teil. I (Leipzig) 1(1): 478 (1897).
Other accepted species: Species Fungorum – search Myrmaeciella.
